Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new types. The new products enable users additional flexibility of their methods without shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides much more
safety within the drivetrain in many functions. The coupling variant allows users to
specify a most torque so that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected against overload and
harm, thus significantly rising system availability.
With เพรสเชอร์เกจnuovafima -Eupex B plus clamping element, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft finish is connected to the coupling hub by way of a clamping
connection with no feather key and service capability is increased. For instance,
assembly or replacement of worn elastomers can be carried out much more easily.
No connecting machine elements have to be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a new double-cardanic coupling is introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with commonplace growth items for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
The shortened general length allows cost-optimized use with a small shaft distance
dimension with out losing the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber elements made from NBR, Flender now also offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the ability density to be elevated by another 20 percent on
average. For sizes 300 and above, the acquainted NBR elastomer is mixed with
cloth inserts and the torque capacity is again raised.
“With a view to the long tradition of cam couplings, our growth engineers are
systematically engaged on rising the number of combinations even additional. The
2022 enhancements give our users a variety of sustainable options for
optimizing their machines and methods much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
